WASH-TUB.

SPECIFICATION forming part of Letters Patent No. 445,643, clated February 3, 1891. Application filed .Tune 3, 1890. Serial No. 354,l86. (No model.)

To all whom 't may concern:

Be it known that I, J OSEPH KELLoW, a citizen ot' the United States, residin g at Brooklyn, in the county of Kings and State of New York, have invented a new and useful Slate Tub, of which the following is a specification.

This invention has relation to improvements in slate tubs usually employed for laund-y purposes; and the obj ects of the invention are to im prove the general construction of the tub, and especially to 'provide for an expanson of the sides of the tub when hot water is introduced therein, and to obviate the usual crushing strain brought upon the slaty material by the bolts by reason of such expansion,

and withal to provide a tight and efficient joint..

\Vith the above main objects in view the invention consists in certain features of construction hereinafter specified, and particularly pointed out in the claims.

Referring to the drawiugs, Figure 1 is a perspectve of a tub construct-ed in accordance with my invention. Fg. 2 is a longitudinal vertical section. Fig. 3 is a transverse section at one side of one of the end walls. Fig. 4 is an end perspective of a portion of the tub, illustratingamodificationofthebinding-plate. Fig. 5 is a detail in perspective of the elastic pad.

Like numer-als of reference indicaterlike parts in all the figures ot' the drawings.

In practicing my invention I provide the usual vertical rear wall l, and the usual inclined front Wall 2, each ot' which is near its two ends and at its center provided with vertical grooves or recesses 3 for the introduction' of the two end walls 4 and the central partition 5. By reason of the location of the outer grooves the ends ot' the walls l and 2 extend beyond the outer sides or surfaces of the end walls 4.

6 designates the bottom of the tub, and the same is let into a longitudinal groove 7, formed in each of the walls l and. 2 near their lower edges, and said bottom is provided with opposite transverse end and central grooves 8, which receive the lower rabbeted edges of the walls et and partition 5. The parts as thus constructed are cemented by some suitable cement so as to form thoroughly water-' tight joints, as is usual in this class ot tubs.

Near their outer ends each of the side walls 1 and 2 is provided with opposite pairs of bolt-openings 9, which openings register with each other and With grooves 10 i'ormed in the outer surfaces of the end walls t. Opposite the openings 9, and upon the outer sides of the front and rear walls, are applied rubber pads or washers 11, which pads or washers are preferably upon one of their surfaces provided with a series of in this instance longitudinal serrations or grooves, or, as will be apparent, said serrations nay be onitted. The openings 9 are continued through these pads and also through opposite bindingplates 12, as at 13, which are applied to the outer sides of each of the pads or washers. Binding-bolts 14 are now passed through the openings 9, 10, and 13, and to the ends of the s' tne are applied binding nuts or caps 15.

16 designates inverted-L-shaped bindingbolts, which, after entering sockets 17, forrned in the outer walls 4, have their lower stems or threaded ends projecting down through openings 18 formed at the outer ends of the bottom section 6. One of these bolts is employed at each end of the tub and serves' to hold the bottom snugly in position. The lower ends of the bolts are provided With nuts 19, and between the nuts and the bottom section are binding-plates 20.

In the main figures of the drawings I have illustrated the bindingplates 13 as being forned of light angle-iron; but it Will be apparent that plain sheet-iron may be employed, as shown in the modification heretofore mentioned.

From the above Construction it will be apparent that the strain otthe bolts comesagainst the slate sections only through the rubber packings or washers,wlich obviates the erushing strain which has heretofore been a great drawback to the practicability of this class of tubs. The resiliency or elasticity of the rubber packing is bountit'ully sufiicient to pernit of any ordinary expansion of the sides of the tub Without in any way endangering the same or rendering it liable to fracture.

Having thus described my invention, what I claim isl. In a tub of the class described, the conbination, With opposite side and end sections, the letter-being let into and within the edges of IOO 'tom sections, suitabiy connected or jointed,

said sides beyond the ends being provided with pairs of opposite openings and the ends with transverse grooves aligning with the openings, of transverse binding-bolts provided with binding-nuts, clamping-piates mounted between the nuts and heads of .the

bolts andthe sides, rubber packings mounted between the piates and the sides, andinverted- L-shaped bolts, one located at each end of the tub, and having their L ends projected into sockets fol-med in the ends and their lower ends extending through openngs formed in the bottoms, securing piates mounted over the en ds of said bolts, and caps mounted on the bolts over the plates, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affiXed my signature in presence of two witnesses.
